Grignard reaction Abstract: In this laboratory‚ triphenylmethanol was synthesised from reacting benzophenone and bromobenzene using Grignard reaction. As the reaction was to set up to produce a Grignard reagent and then recrystallize it to obtain pure sample. The percentage yield obtained was 55% and its melting point was 161 co which is within the literature value 160-163 co. In addition to that the IR spectroscopy confirmed the molecule structure to be triphenylmethanol. Introduction: The Grignard

the hot water bath for around 5 minutes. The aldehyde functional group was the reducing agent in reducing sugars and they all had a positive result was because of their ability to act as a reducing agent during the Benedict’s test. A reducing agent donated electrons during a redox reaction and was itself oxidized. Reducing sugars had either an aldehyde functional group or have ketone group – in an open chain form – which can be converted into aldehyde (Sur‚ B. K.‚ R. K. Shukla‚ and V.S Agashe‚ 1972)

Introduction An essential oil is a concentrated hydrophobic liquid containing volatile aroma compounds from plants. Essential oils are also known as volatile oils‚ ethereal oils or aetherolea‚ or simply as the "oil of" the plant from which they were extracted‚ such as oil of clove. Volatile oils are the odorous and volatile products of various plant and animal species. As they have a tendency to undergo evaporation on being exposed to the air even at an ambient temperature‚ they are invariably termed

use of wet chemical tests. In this manner‚ Unknown A which was a colorless solution‚ was first tested with 2‚4-DNP which after mixing for a few seconds formed a bright yellow precipitate. Although this confirms the presence of either a ketone or aldehyde group‚ one simple chemical test does not completely specify the presence or absence of other functional groups. Therefore‚ a second test was made in order to test for the presence of alkyl halides (R-Br or R-I specifically). However‚ after the addition

Aliphatic hydrocarbons are divided into three classes: alkanes (e.g. methane‚ ethane and propane) have only single bonds‚ and are said to be saturated; alkenes (e.g. ethene and propene)
